Ajax Codeigniter variable problem

I have a question, and I don't know if I'm posting it on the right place of the forum. I'm trying to do a form with Ajax to count my clicks through Ajax. But the problem is that every time I do a click I always receive the number of clicks as 1.

Here's a piece of the code explained:

In JavaScript from the View

$("#click").click(function(){    
            $.ajax({
                type: "POST",
                url: bseUrl+"counter/incCount",
                data: click,
                success: function(html){
                    alert(html);
                }
            });
        });

The alert(html) should show the total clicks from the server;

counter controller

class Counter extends CI_Controller {

    //put your code here
    var $numClick;

    public function __construct() {
        parent::__construct();
        $this->numClick= 0;
    }

    public function Counter() {
        parent::__construct();
$this->numClick= 0;
    }

    public function incCount() {
        echo $this->numC开发者_JS百科lick++;
    }

public function index() {
        //loadView
    }
}

But every time I click I'm always receiving the number of clicks as 1. Why am I losing the variable content every time? it seems that every time I do a Ajax call I'm starting the variable.

Can you guys help me?

You are re-initializing the counter every time you call click handling function - why? try doing it this way:

//init counter somewhere
var num_clicks= 0;
//increase counter and send request
$("#click").click(function(){
            num_clicks++;
            var click= "numberClick="+num_clicks;
            $.ajax({
                type: "POST",
                url: bseUrl+"counter/incCount",
                data: click,
                success: function(html){
                    alert(html);
                }
            });
        });
